EXCEL-II DES to Treat the Patients With de Novo Coronary Artery Lesions. (CREDIT-III)
A Prospective Multicenter Single-Arm Observational Registry Study to Assess the Safety and Efficacy of EXCEL-II With Sirolimus Eluting Stent for the Treatment of Patients With de Novo Coronary Artery . (CREDIT-III Trial)
The study aims to further assess the safety, efficacy and the performance of its delivery system of the new generation Sirolimus-eluting stent of JWMS up to five years.
  1. A prospective, a single set, multicenter clinical trial;
  2. The primary in situ in patients with coronary heart disease;
  3. The center of: 28 (the actual number of center shall prevail);The plan selected 621 patients;(where the total number of cases in 2.25 mm specification not less than 30 cases, 5 cases each specification of not less than 2.25 mm.)
  4. Clinical follow-up time points: 1 months, 6 months, 12 months and 18 months of a year and 2 years to 5 years follow-up; This test by an independent coronary angiography core laboratories, data management and statistical center, clinical end points to judge committee and clinical monitoring of all relevant clinical and imaging data collecting, sorting, statistical analysis and judgement.All the selected patients within five years continuous follow-up tracking (phone or outpatient follow-up), to observe the happening of adverse events to the forward of the second generation of EXCEL drug-eluting stents (des) system security to make more accurate and credible evaluation.
Observational [Patient Registry]
Observational Model: Case-Only
Time Perspective: Prospective
5 Years
Retention:   None Retained
According to the CREATE (Multi - Center Registry of Excel Biodegradable Polymer Drug Eluting Stent) registration results show that ExcelTM drug-eluting stents implanted an average of 12 months, target lesion (TLF) the failure rate of 6.7%.Will this study expected target lesion group stent failure rate estimate of 6.7%, the target is 9.5%;Test hypothesis: bilateral 0.05% 0.05%, master degree, clinical follow-up requirements is more than 95%, this research need at least 829 patients, remove the CREDIT II randomized controlled study can provide the number of cases of test group 208 examples, this study still need to be included in the 621 patients.
